The Devils know they are in the playoffs, and could find out whom they face in the first round as soon as tonight. But that’s not important to them. Finishing the season strong is what counts.

“You still have to play the three games, so it’s not going to matter how other people are doing or not doing,” defenseman Bryce Salvador said after practice yesterday. “The focus is on our team play and making sure that we are mentally ready for the playoffs. You want to go into the playoffs feeling good about your team.”

Winners of three straight heading into tonight’s game in Newark with the Islanders, the Devils have scored 11 goals in their past two games after scoring 11 in regulation over the prior eight. They are the only team to boast three 30-goal scorers (Ilya Kovalchuk, 34; Zach Parise, 31; David Clarkson, 30) and four 25-goal scorers (Patrik Elias, 25).

“I don’t remember the last time we have had that many guys with 25 goals, so it’s a big help,” Parise said. “Playoff time, you need everyone to contribute at a different time, so it’s a good thing for us and it makes it tougher to defend, too.”

The last time the Devils were in the playoffs, they lost to the Flyers in the first round in 2010, scoring nine goals in the five games. The Devils long have been a defense-first team, but will need all of their offense in the postseason — especially since playoff games are not decided by shootout, where they have a 12-4 record.

“You may have a couple of situations in the playoffs where you’re going to get four, five, six goals, but you can’t be going into the playoffs with that mentality,” Bryce Salvador said.

* Clarkson did not practice, getting a maintenance day according to coach Peter DeBoer. … First-round playoff tickets go on sale this morning at 10 a.m. They can be purchased through Ticketmaster, the Devils website or the Prudential Center box office.
